Sometimes we may wish that we were able to travel back in time to see Jesus and hear him teach. We think that we might be able to know more about him if we could just hear him speak to us in person. Yet, this passage assures us that we can understand him perfectly well right where we are. In fact, we are better off, since we live in the age ofthe Holy Spirit, which is better than the one before. During this age, the Holy Spirit is helping all Christians to understand Jesus properly, and is using them to do great works.
Though Jesus is going away, the disciples will continue his work inthe power of the Holy Spirit during this age. The light of the world will shine through them, exposing the deeds of darkness that people do (Ephesians 5:11). The result is that some people will be convicted of theirsin and be driven to repentance, though others will merely hate the light.
